Method and elevator control arrangement for controlling a maintenance mode of an elevator system

An elevator control arrangement for controlling a maintenance mode in an elevator system, the elevator control arrangement comprising:

• a machine-detectable feature within the elevator system that can only be detected by a portable computer-controlled device that is located outside an elevator shaft of the elevator system and wherein the machine-detectable feature is uniquely assigned to the elevator system;
• wherein the machine-detectable feature is an optically recognizable feature arrangement that is uniquely assigned to the elevator system and the portable computer-controlled device detects the machine-detectable feature by optically recognizing the optically recognizable feature arrangement;
• wherein the portable computer-controlled device is adapted to automatically recognize the machine-detectable feature and, in response, output a maintenance completion signal;
• and
• an elevator controller for controlling the maintenance mode that is adapted to complete the maintenance mode in response to receiving the maintenance completion signal.

A method for controlling a maintenance mode operation of an elevator system, the method comprising the steps of:

• recognizing a machine-detectable feature automatically using a portable computer-controlled device of a technician, wherein the machine-detectable feature can only be detected by the portable computer-controlled device when the portable computer-controlled device is located outside an elevator shaft of the elevator system, and wherein the machine-detectable feature is uniquely assigned to the elevator system;
• outputting a maintenance completion signal from the portable computer-controlled device in response to the recognition of the machine-detectable feature;
• receiving the maintenance completion signal, or a further maintenance completion signal output in response to the maintenance completion signal, by an elevator controller controlling the maintenance mode operation of the elevator system;
• wherein the portable computer-controlled device outputs the maintenance completion signal to an external data cloud and in response the further maintenance completion signal is output from the data cloud to the elevator controller;
• wherein the portable computer-controlled device outputs the maintenance completion signal together with an identification signal that uniquely identifies the elevator system to the external data cloud and the further maintenance completion signal is output from the data cloud to the elevator controller of the elevator system indicated by the identification signal;
• and
• completing the maintenance mode operation by the elevator controller.
